Can Anxiety Cause Constipation?


One possible cause of constipation is anxiety and stress. Constipation can mean that you aren’t passing stools regularly or are unable to entirely empty your bowel. As a result, you may also feel bloated, feel sick and/or have a stomach ache.

Why Can Anxiety Cause Constipation?

As with a lot of physical symptoms of anxiety, the triggers lie within our caveman brain. This is the survival-driven part of our brain that our newer, rational cortex grew on top of. Its primary concern is keeping us alive, so when our brain perceives a threat, it releases the stress chemicals cortisol and adrenaline and activates the stress response called the fight, flight or freeze response. 

Your gut and brain communicate with each other through The Gut-Brain Axis, meaning there is a bidirectional link between the central nervous system (CNS) and the gut’s enteric nervous system (ENS). In other words, how you feel can impact your gut and vice versa. The stress responses can cause changes in the gut and so can aggravate or cause constipation.

For example, the stress response also prompts your body to divert blood flow away from your intestines towards your vital organs, such as your lungs and heart, which causes your intestinal movement to slow down. The stress response can also suppress digestion and digestive enzymes as well as cause stomach muscles to tighten. Any of these changes can lead to constipation. 

Also, if you experience stress and anxiety frequently, you can develop chronic stress, also known as hyperstimulation, which is when your stress response is on high alert for a prolonged period of time, long after the perceived threat has passed. Hyperstimulation can cause prolonged digestive system disruptions, which can lead to chronic constipation. 


How Can I Stop This Symptom?

As this symptom stems from our fight, flight or freeze response, the main thing that we can do to combat it is to focus on our breathing, adopting anxiety-reducing breathing techniques, such as controlled diaphragmatic breathing or box breathing. This should calm our central nervous system, distract our mind from the perceived threat, and deactivate our fight, flight or freeze response allowing our rational brain to kick back in and regain a semblance of control and feel the black cloud lift. 

Though this will help short-term, in order to prevent the symptoms of anxiety and stress occurring in the first place, you need to manage or build strategies to tackle your anxiety and stress. There are several options available including CBT (Cognitive Behavioural Therapy), mindfulness, medication and group therapy. If you’re unsure, please contact your GP for more information.

Constipation and related symptoms can also be caused by other factors, so talk to your doctor to find the root cause and therefore the best course of action.
